Kaizen Windows & Doors plans coloured uPVC window replacement in Cheadle (Staffs) around details that are harder to correct after finishing, with frame position kept as the lead check for this coloured uPVC windows scope. The first control is frame position, and we set the new frame at a position that works with the reveals, sill and external finish, with frame position kept as the lead check for this coloured uPVC windows scope. We then coordinate frame alignment through frame finish, trims, sealant colour, adjoining masonry or render and hardware and check the frame for line, level and square before glazing and final tightening, with frame position kept as the lead check for this coloured uPVC windows scope. Glazing Beads is checked before closure, while opening survey is included in final handover. We check bead seating and corner joints after the glass is installed and check the existing opening, frame position and surrounding finishes before final dimensions are confirmed, keeping the installation focused on a coloured window finish coordinated with the surrounding external materials, with frame position kept as the lead check for this coloured uPVC windows scope.
